蛇纹石矿物作为润滑油添加剂对锡青铜摩擦学行为的影响

Effect of Serpentine Mineral as a Lubricant Additive on the Tribological Behaviors of Tin Bronze

  • 摘要: 采用SRV滑动磨损试验机考察了蛇纹石天然矿物粉体作为添加剂对油润滑条件下与钢对磨时锡青铜摩擦磨损的影响. 借助扫描电镜、能谱仪、X射线光电子能谱仪、纳米压痕仪等对磨损表面形貌、元素组成与化学状态,以及纳米力学性能进行了分析,探讨了蛇纹石添加剂改善锡青铜摩擦学性能的作用机制. 结果表明:蛇纹石矿物在锡青铜表面形成了1层由金属氧化物、氧化物陶瓷、石墨和有机物构成的复合摩擦反应膜,其纳米硬度和弹性模量呈表面低、内部高的梯度变化,从而显著改善了油润滑条件下锡青铜的摩擦学性能.

     

    Abstract: The effect of serpentine natural mineral powder as a lubricating oil additive on the friction and wear of tin bronze was investigated by using a SRV sliding wear tester. Scanning electron microscope, energy dispersive spectroscopy, X-ray photoelectron spectroscopy, and nanoindentation tester were employed to determine the elemental composition, chemical state, and nano mechanical properties of the worn surfaces. The friction reducing and lubricating mechanism of the serpentine additive was discussed. Results show that a tribofilm composed of metal oxides, oxide ceramic particles, graphite, and organics was formed on the tin bronze worn surfaces lubricated with oil containing the serpentine mineral. The nano-hardness and elastic modulus of the film demonstrated the gradient variation that low in the surface and high in the subsurface, as contributed to the improvement of the tribological behaviors of tin bronze.
